Wynn has been a prolific Republican donor, particularly over the past decade: He has donated more than $2.5 million to the Republican Governors Association since 2012 and has been a top donor to several individual gubernatorial campaigns.

The casino mogul also contributed $411,000 to the National Republican Senatorial Committee over the past five years, $248,000 to the RNC and $100,000 to the National Republican Congressional Committee, according to campaign finance records.

In a statement issued on Friday, Wynn said the allegations are “the continued work of my ex-wife Elaine Wynn, with whom I am involved in a terrible and nasty lawsuit in which she is seeking a revised divorce settlement. The idea that I ever assaulted any woman is preposterous. We find ourselves in a world where people can make allegations, regardless of the truth, and a person is left with the choice of weathering insulting publicity or engaging in multi-year lawsuits.”
